Struct MotionStateMap 

pub struct MotionStateMap {
    pub values: HashMap<(WidgetId, MotionPropertyId), MotionValue>,
    pub active: HashMap<(WidgetId, MotionPropertyId), ActiveMotion>,
    pub presence: HashMap<WidgetId, PresencePhase>,
    pub ripples: HashMap<WidgetId, Vec<SpawnedRipple>>,
}

Runtime storage for active motion values.

Shells own this through crate::RuntimeState. Tests and custom renderers may inspect it to read deterministic motion progress.

Fields

values: HashMap<(WidgetId, MotionPropertyId), MotionValue>

Last known value for each (widget, property) pair.

active: HashMap<(WidgetId, MotionPropertyId), ActiveMotion>

Active transitions keyed by (widget, property).

presence: HashMap<WidgetId, PresencePhase>

Current presence phase for each presence id.

ripples: HashMap<WidgetId, Vec<SpawnedRipple>>

Active ripple instances for each ripple layer.

Implementations

impl MotionStateMap

pub fn scalar_value( &self, widget_id: WidgetId, property: MotionPropertyId, ) -> f32

Returns a scalar-like value for a widget/property pair.

If no value has been produced yet, the property’s default value is used.

Trait Implementations

impl Clone for MotionStateMap

fn clone(&self) -> MotionStateMap

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MotionStateMap

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for MotionStateMap

fn default() -> MotionStateMap

Returns the “default value” for a type.
